Embodiment Construction

[0020] Systems, methods, and apparatus are described herein that generally relate to providing common access to process image data across multiple automation devices using a process image backbone. A process image backbone is a form of middleware that essentially "glues" together the runtime environments of the different controllers and other field devices in the automation environment. Using the process image backbone, various devices conceptually share one large process image. Thus, the device can interact with the process image data of the remote device in substantially the same manner as the local process image data of the device. As described in further detail below, various techniques may be used to support the transparency and connectivity provided by the process image backbone. For example, tagging data with identifiers that give patents to the data source. An analogy can be drawn to a computer system where in some implementations a local file can be addressed using ...

Abstract

A system for providing access to locally stored process image data to other devices in an industrial production environment includes a plurality of controller devices and a process image backbone. Each respective controller device comprises the following: a volatile computer-readable storage medium comprising a process image area; a non-volatile computer-readable storage medium; a control programconfigured to provide operating instructions to a production unit; an input / output component configured to update the process image area during each scan cycle or upon the occurrence of one or more events with process image data items associated with the production unit; and a historian component configured to locally store the process image data items of the process image area as time series datain the non-volatile computer-readable storage medium. The process image backbone provides the plurality of controllers with uniform access to the process image data items of each programmable logic device.

Description

technical field [0001] The present disclosure is generally concerned with providing common access to process image data across multiple automation devices using a process image backbone. The various systems and methods can be applied to industrial automation applications, as well as various other applications using controllers. Background technique [0002] The controller is a dedicated computer control system configured to execute software that continuously collects data about the state of the input devices to control the state of the output devices. Examples of controllers include programmable logic controllers, motion controllers, CNCs, intelligent I / O, and drive controllers. A controller typically includes three main components: a processor (which may include volatile memory), volatile memory including an application program, and one or more input / output (I / O) for interfacing to other devices in the automation system. O) port. Modern controllers have their own process...
